'The Office' Season Finale: Jim Carrey Joining Dunder Mifflin

Dunder Mifflin just got a late entry into the job applicant pool.

It was announced on Thursday that Jim Carrey will appear in the season finale of "The Office," joining a deep roster of guest stars that will grace the screen during the 50-minute long special. The question is whether this more than just a one-off appearance.

It was announced in March that Will Arnett and series creator Ricky Gervais would guest star in the finale, while earlier in April Ray Romano, James Spader and Catherine Tate were added to the episode. All five have been teased as potential longterm hires, though Arnett, Gervais and Romano, because of previous commitments, are unlikely to be the choice. Ferrell, who was supposed to appear in the season finale, will now no longer do so.

With Carrey being added as a late entrant, the future of Dunder Mifflin gets even murkier. Executive producer Paul Lieberstein, who also plays Toby on the show, recently revealed that current employees will make a play for the job, though it doesn't seem there's much of a chance that they'll be hiring from within.

"The show sans-Steve it's a whole new show so we're actually really excited," he said. "The last two episodes this year are without Steve and without Will and they were awesome. They were really, really fun and as much as we will miss Steve for sure it's kind of great to pick up this show in a whole different way. It's really fun."

Interestingly, he also said he didn't know who Carell's replacement would be, and that there may not be a replacement so much as there is "a shift" in the show. Given that they've already filmed the final two episodes, Krasinski was either showing off his acting skills, or there is truly a surprise in store.
